Laravel 5.2 Multi-Auth with API guard

Hi all. I'm trying to get a multi auth system working where Users can log in via the normal web portal, but a separate database of entities called Robots can also log in via an API guard style token driver. I'm very excited about how easy 5.2 is supposed to make this but I can't seem to get it working - no matter what I do, the setup I have is not directing my auth guard to the correct Robot database and keeps trying to authenticate these requests as Users via tokens (which fails, because users don't have tokens).
